Your trusty iPhone is always there when you need it. Say you’re in a new town and you needed to turn on the GPS to find your way only to find it dying on you moments later. The battery life on the iPhone 4 can be pretty dismal when GPS, Wifi or Data Roaming is turned on. Thankfully there’s some pretty decent battery cases that comes in all kinds of sizes which combines both external battery and the case. Here are some of the best battery cases for the iPhone 4 that not only give you battery boost but also protection from bumps and scratches.

This is an attractive battery pack that fits the new iPhone 4 perfectly and offers a good battery boost too. It has a power button for you to charge the phone when you want it to. However it’s slightly bulky and shiny black surface picks up fingerprints easily.

Even though this battery pack is rated at 1500 mAh compared with Mili’s 1600 mAh, but the Mophie exhibited equivalent performance. Though more expensive, it justifies itself by not only protecting your phone, it is solidly built but still thin and oozes class as well. Mophie is clearly one of the best battery case out there in the market.

Another solid and sturdy battery case in great looking glossy white color which doesn’t scratch easily and also has LED power indicator that flashes when battery is low. uNu also has a power button to toggle charges on/off. Great battery life and a cheaper price makes this battery case a great buy. There’s also a black version available.

Boost Case Plus is the more power packed original Boost Case with an increased capacity of 2200 mAh and it also fits both the iPhone 4 and iPhone 4S. A well built case that’s not as bulky as you would expect even with the extended power that is capable of doubling your original iPhone 4 battery life. It’s an Apple Certified case that lets you sync and charge simultaneously without needing to disconnect.
